VIRTUAL CLUSTER ESTABLISHMENT METHOD AND NETWORK DEVICE

摘要

The present invention provides a virtual cluster establishment method and a network device. The method includes: a first network device establishes, a network-layer-based first communication connection with a second network device; the first network device sends a first registration request message to the second network device through the first communication connection, where the first registration request message is used to establish a virtual cluster with the second network device; after the first network device receives a registration response message, selecting the second network device as an active main control device in the virtual cluster system; establishes, a network-layer-based second communication connection with a third network device; sends, a second registration request message to the third network device; and selects the third network device as a standby main control device. In this invention, a structure of a cluster is simplified, and scalability of the cluster is improved.

1. A virtual cluster establishment method, comprising:
establishing, by a first network device, a network-layer-based first communication connection with a second network device; sending, by the first network device, a first registration request message to the second network device through the first communication connection, wherein the first registration request message is used to request to establish a virtual cluster with the second network device; after the first network device receives a first registration response message sent by the second network device, wherein the first registration response message indicates that the virtual cluster is successfully established, selecting the second network device as an active main control device of the first network device in the virtual cluster; establishing, by the first network device, a network-layer-based second communication connection with a third network device; sending, by the first network device, a second registration request message to the third network device through the second communication connection, wherein the second registration request message is used to request the third network device to join the virtual cluster; and after the first network device receives a second registration response message sent by the third network device, selecting the third network device as a standby main control device of the first network device in the virtual cluster.
